He sure does! I'm having him build my rifles before everyone finds out about him and he gets too busy

225 ELDM's with 84gr. H1000 and a CCI 250
A little stiff bolt lift. So going to shoot 83gr. next.
208 ELDM's also showed promise. First 4 were touching, then shot #5 turned it into a .8" group. Then shot 3 at 522 yards really quick for a 3.5" group. 88gr. H1000 was also giving me some bolt lift. So shooting 87gr. next.

I would have thought the velocities would be higher. My 300 PRC is getting 2871 average with the 225 ELDM 78.3 grains of Retumbo and 2956 average with the 215 Hybrid and 78.5 grains of H1000. Neither show any pressure signs. I am at 6X fired on the brass and the primer pockets are still tight.

Honestly this chamber just is not optimized for H1000. Just wanting to use it because it's so clean and consistent.
I was actually using brass that was fired in another chamber yesterday because I didn't have my personal formed brass prepped yet. Shot my own brass this morning and didn't see any pressure signs with either bullet.
May have just been a slight discrepancy between the two chambers giving me the bolt issues. I should know by now to only use brass shot in my own chamber, but I couldn't wait and already had the other brass prepped and waiting lol.

Did more testing in my own fired brass. None of these charges showed any pressure. I had my suspicions when I tested 87gr. and had zero signs after swapping brass.

Couple of groups with 208 ELDM's and 89 & 90gr. Retumbo. Just a little too much ES for me. But averaged 3090fps and 3130fps

225 ELDM's have just shot the most consistently small groups and tightest ES. And if I really crunch the numbers, other than drop, they outperform the 208's past 800 yards. And nothing inside 800 yards will know the difference by getting hit by either bullet.
84gr. H1000 at 2950fps .37" 5 shot group last night. Going to set up some paper and test 84, 84.5 & 85gr. at 600 yards to see if there's a discernible in accuracy at any of the charges. 84gr. has absolutely zero pressure signs.

Evening shoot at 600 yards. 225 ELDM and H1000. Slight right to left wind. Just held same POA for each shot. I was dialed .2 Mil low for each group.
Beautiful rifle. Any reason you went with the NF over the ZCO?

That actually was my last shot at 84, yes. I shoot 5 straight, but about 1 minute between shots. Just laying behind the rifle and taking a short pause between rounds. Don't know if it makes a difference or not. I just do it.

Just dependable durability. ZCO glass is unreal and the ATACR really doesn't even come close in that department. But the ZCO's just aren't proving to be near as durable. Which is the most important thing for me. So I went ATACR.
